How to deal with construction waste
Resourceful recycling of construction waste in developed countries has made great achievements. According to relevant information, Japan's construction waste resource utilization rate has reached 98%, and the application guidelines for recycled aggregates and recycled concrete were formulated in the 1970s. In addition, the Japan Science and Technology Agency has set the recycling technology as one of the ten most emerging technologies in the next 30 years. The average comprehensive utilization rate of EU countries has exceeded 70%.
Construction waste resourceization, completely changed the traditional economy "resources - products - pollution emissions" one-way flow of the linear economic model, the full realization of the circular economy The feedback process of "resource - product - renewable resource - new product" is fully realized. At present, the construction waste treatment crushing plant has become the core equipment of construction waste crushing and treatment. The tire type mobile crushing plant developed and produced by our company is a highly integrated and modular crushing and treatment equipment integrating various technologies such as feeding, conveying, coarse crushing, medium crushing, fine crushing, screening and dust removal. It not only realizes the recycling of traffic and construction waste, but also has no dust pollution and small footprint, realizing the good effect of high efficiency, energy saving and environmental protection.
Construction waste treatment crushing plant includes: hydraulic jaw crushing mobile crushing plant, impact crushing mobile crushing plant, cone crushing mobile crushing plant, impact crushing mobile crushing plant, mobile screening plant, jaw crushing fixed crushing plant, impact crushing fixed crushing plant, cone crushing fixed crushing plant, impact crushing fixed crushing plant, fixed screening plant, crawler type mobile crushing plant, etc.. Among them, the crawler type mobile crushing plant and tire type mobile crushing plant can carry out coarse, medium and fine crushing of construction waste. The equipment is flexible, convenient and highly mobile, which can save a lot of infrastructure and relocation costs; it can crush materials on site without transporting them away from the site and crushing them again, and can move with the advancement of the raw material mining surface, thus greatly reducing the material transportation costs. The configuration of mobile crushing plant is flexible and can be adapted to the actual site design or special mobile crushing plant to design the corresponding construction waste treatment process.
Uses of construction waste after recycling and treatment:
1. many wastes in construction waste can be reused as renewable resources after sorting, rejecting or crushing, such as: scrap steel, scrap iron wire, scrap electric wire and various scrap steel parts and other metals, which can be reprocessed and manufactured into various specifications of steel after sorting, concentration and re-furnace;
2. waste bamboo wood can be used to manufacture artificial wood;
3. Brick, stone, concrete and other waste materials can be crushed and used instead of sand for masonry mortar, plastering mortar, playing concrete bedding, etc. It can also be used to make building materials products such as blocks, paving bricks and lattice bricks.
